I wasn't complaining that you didn't change the indentation of the other lines (though neither would I complain if you did). But either there should be one space between bool and processFullBuffer (my preference) or else the variable name should line up with the ones above. This does neither, which is why I said it was weird.

I prefer to refactor code to be correct than to make 'minimal changes', in general (there are cases where I may argue the opposite, but this is not one of them). Changing an interface (unless it's exposed to external code) is not something we are scared of.
